Forum: prelinger Subject: Re: Why were the mpeg2 files created in a non-compliant DVD format?

I don't think it was mentioned in the earlier thread, but you'll notice the older films' mpeg2s split the film into file sizes that fit on CD. I would guess that the reduced horizontal resolution was also choosen because it helped reduce file size. I'm sure the Archive has access to the originals, but it's a huge number of films, so I'd bet re-encoding is unlikely to happen any time soon. The newer (within the last couple of years) mpeg2's in the Prelinger Archive are 704x480 and burn fine looking DVD's.

You said there's no way to burn DVD's from the non-comlaint mpegs, but that's not really true. You can re-encode them. In fact the authoring program that came with my burner will do it automatically, and any low cost video editing program (Videowave, Video Explosion Deluxe, Video Studio - each under $100) could do it as well and let you edit together films that have been split into parts at the same time. There are probably some free utilities that can re-encode too.

Sound sync problems are common in both mpeg1 and 2 players, esp. if you try to skip ahead or fast forward a clip. It is possible to get the sound sync off in the encoding, but I haven't had any sync problems playing from the start and just letting them go.
